To turn the unit off:
1. Press and hold the down arrow for five seconds.
BRIGHTNESS CONTROLS
The Mini A-Spec offers 10 brightness settings. Settings 1 through 3 are best for low light such as dusk or
dark indoor environments. Settings 4 through 7 are best for environments with mid-level brightness such
as normal indoor lighting or cloudy outdoor environment. Settings 8 through 10 are best for very bright,
sunny outdoor environments.
To adjust the brightness:
1. Press the appropriate up or down arrow to adjust the brightness of the dot.
2. To increase brightness press the up arrow.
3. To decrease brightness press the down arrow.
Note: The last brightness setting used prior to deactivation will be the same setting next time the unit is activated.
MOUNT TYPE
The Sightmark Mini A-Spec includes a low-profile mount (10) and AR riser mount (9) for absolute
co-witness. If mounting on a bolt-action hunting rifle or shotgun, the low-profile mount (10) is
recommended. If mounting on flat top AR-15 rifle, it is recommended the AR riser mount (9) be
installed for an absolute co-witness with iron sights.
To remove the base:
1. Use the included torx key to loosen and unscrew the two assembly screws (7) attaching the sight to
the mount.
2. Separate the sight from the mount.
3. Select the desired mount to attach the sight to.
4. For a semi-permanent fixture, a
small amount of blue Loctite® may
be applied to the threading of the
two assembly screws. Tighten and
secure the two screws by applying
20-inch pounds of torque.
(Do not overtighten.)
MOUNTING
The Mini A-Spec is designed to mount to both Weaver and Picatinny rails. For safety, it is best to have
at least three to four inches of eye relief.
To mount:
1. Loosen the mounting screw (7) on the mount. Attach the Mini A-Spec to the firearm’s rail with the
objective lens (1) facing toward the muzzle.
2. Make sure the recoil bolt is positioned in the groove of the rail and the unit is fully seated on the rail.
3. Tighten the hex nut to 35 to 45 in/lbs of torque using the included hex wrench. Do not overtighten.
The Mini A-Spec is compatible with optic-ready pistols such as the S&W® M&P® Core® and Glock ® MOS
pistols. It can also be installed on specific handgun models with the purchase of Sightmark pistol mount
accessories. Pistol mount bases include:
Beretta® for models 92/96/90-TWO
1911 standard
Glock® with standard frame (1.18” width)
Sig Sauer® P226
Springfield® XD models
Smith & Wesson ® M&P models
HK® USP
To install the Mini A-Spec on an optic-ready pistol, follow the manufacturer’s mounting instructions.
The pistol manufacturer’s mounting hardware and screws should be used to mount the Mini-Shot
A-Spec.
To install the Mini A-Spec onto a pistol using a Sightmark pistol mount base please read the following
instructions. It is recommended to use a qualified gunsmith to remove the rear sight from your
handgun. Using improper tools or improvised removal methods can damage your pistol. Once the
rear sight is removed:
1. Remove the pistol mount base and dovetail piece from the packaging.
2. Insert the dovetail piece into the slot where the rear sight was installed.
3. Next, the mount base is placed on top of the slide over the dovetail. Secure the two Philips
screws by applying 20-inch pounds of torque. Once tightened the dovetail and baseplate will
provide a press fit. For a semi-permanent fixture, a small amount of blue Loctite® may be applied
to the threading of the two screws.
4. The Mini A-Spec is then placed on the mount base. The four holes on the bottom of the Mini
A-Spec will align with the four pins on the mount base.
5. Secure the Mini A-Spec to the mount base using the two hex screws that were included with
your pistol mount base. Secure the two Philips screws by applying 20-inch pounds of torque. For
a semi-permanent fixture, a small amount of blue Loctite® may be applied to the threading of the
two screws.

OPERATING THE WINDAGE AND ELEVATION ADJUSTMENTS
The Sightmark Mini A-Spec has built-in windage and elevation adjustments (2, 3) with clicks. The Mini Shot
has 1 MOA clicks so each click moves the point of impact 1” at 100 yards, ½” at 50 yards, and ¼” at 25 yards.
In order to make windage and elevation adjustments:
1. Use a flathead screwdriver to make adjustments or “clicks”.
2. Turn the adjustments in the appropriate direction needed to change the point-of-impact as indicated
by the “UP” and “R” arrows marked on the adjustments.
3. For elevation adjustment, turn the adjustment counterclockwise to adjust the bullet’s point of impact
up. Turn the adjustment clockwise to adjust the bullet’s point of impact down. For windage
adjustments, turn the adjustment counterclockwise to adjust the bullet’s point of impact right. Turn
the adjustment clockwise to adjust the bullet’s point of impact left.
BORESIGHTING and SIGHTING IN
Boresighting and test firing should be performed safely on a firing range. Laser boresights are a quick
and accurate method for sighting in. Below is how to Boresight, which works best when the unit is
mounted on a rest.
1. When mounting the sight on a bolt-action rifle, remove the bolt; or when mounting to a semi-automatic rifle, disassemble the rifle until there is a straight line of sight through the bore.
2. Use a target at least twenty yards to fifty yards away when sighting in. Look through the bore of the
weapon and locate the bull’s-eye of the target.
3. Sight in the target through the bore and then make windage and elevation adjustments (see
“Operating Windage and Elevation Adjustments” for instructions) to the red dot until the reticle is
centered on the bull’s-eye. To verify the riflescope is accurately sighted in, always fire a three-shot test group at 50 or 100 yards, preferably using the same ammo manufacturer, grain, and lot number.
4. After firing a group use the center of this grouping and make the necessary amount of adjustments to
the elevation and windage adjustments to move your firearm’s grouping to the center of the target.
5. Again fire a three-shot test group to confirm the adjustments. Use the center of the new group to determine final adjustments.
MAINTENANCE
Proper maintenance of the Sightmark Mini A-Spec is recommended to ensure longevity. It is recommended that when the sight becomes dirty, it is wiped down with a dry or slightly damp cloth. Blow dirt and debris off all optics and then clean lenses with a lens cleaning cloth. To remove oils or dried water spots, apply a small amount of denatured alcohol to a lens cloth or cotton swab. Clean the surface of the lens and let dry. Finally use your breath to clean the lens once more. No further maintenance is required. Do not attempt to disassemble any components of the sight.
STORAGE
Make sure that your Sightmark Mini A-Spec is securely attached to your rifle
before storing, and be sure that the reticle illumination is turned off. Cover
with the included rubber cover. Remove the battery if the unit will be stored
for an extended period of time.
WARNING
Before handling the Sightmark Mini Shot M-Spec sight read and understand the contents of your firearm’s manual, and the Sightmark manual. Follow all standard safety precautions and procedures during firearm operation, even when the reflex sight is not in use:
• Avoid hitting or dropping the unit.
• ALWAYS check that the chamber of your weapon is clear before mounting or dismounting the
reflex sight.
• The reticle illumination should be tested during periods of non-use to make sure it is still
operating properly. Failure to follow standard firearm safety precautions and procedures, as
well as the above warnings, is dangerous and may result in serious injury, damage to property,
or death.
TROUBLESHOOTING
Proper authorization is required before shipping any product back to Sightmark. Failure to obtain
authorization could result in your product being returned to the wrong address, lost, or damaged.
Sightmark is not liable for products returned without authorization.
If the Mini A-Spec does not hold zero:
1. Verify the sight is mounted securely to the rifle. If the sight can be shifted in any direction, re-tighten
the mount according to the mounting instructions but do not over tighten. The sight will need to be
re-zeroed afterwards.
2. Be sure to use factory-loaded ammunition of the same bullet type, weight, and, preferably lot number
when sighting in.
The reticle does not illuminate:
1. Check that the battery is in working order and that the polarity of the battery is correct.
2. Check that there is no residue, film, or corrosion on the battery contacts that may be preventing the reticle
from illuminating.
The reticle is blurry and not in focus:
1. Decrease the brightness level of the reticle. The halo or fuzzy appearance is caused by excess
illumination than is required for the current environment the sight is being used in.
2. Make sure the eyepiece lens is clean and does not have any film, fingerprints, or debris covering the
surface. Blow off any debris or dirt covering the lens. Use a lens cloth or q-tip dipped in alcohol to
remove any film or fingerprints.
3. If you are testing the product at a close range, 5 yards or less, to verify its on/off operation, the eye will
accommodate and focus either on the sight’s reticle or the target you are observing not both. Test
the product beyond 5 yards and focus your eye on the target, then the reticle and target should be
in focus.
The reticle illumination turns off while firing:
1. Tighten the battery cap with a coin or flathead screw driver so the cap is fully seated.
